To all whom it may concern Be it known that we, FRANK B. MERRY and Jnssn D. lVARn, both citizens of the United States, both residing at Savannah, in the county of Chatham, State of Georgia, have invented certain new and useful Improvements in Turning and Fluting Machines, of which the following is a specilication.

This invention relates especially to machines for making columns or posts of wood to give to them a round, tapered, or other desired form and to form longitudinal grooves, flutes or ribs thereon for ornamental purposes, and the object of the invention is to provide a machine for these purposes which. is simple in construction, easily operated and which will perform its functions with uniformity and exactness.

In carrying out our invention, we provide a machine having the general form and characteristics of a lathe, being provided with a bed on which head and tail stocks of usual form. are mounted, and the lathe is driven in any suitable way. On brackets extending from the lathe-bed is supported a shelf on which is mounted a lathe-carriage-carrier which is pivotally connected with the shelf and which is controlled in its movement by a pattern secured to the shelf and engaging a roller connected with the lathe-carriage, to which is also connected a rod connected with a weighted lever which holds the roller in engagement with the pattern. carriage is mounted on the carrier and is adapted to move therewith toward and from. the work. The carriage is provided with a nut which engages a screw-shaft within the carrier and this shaft is connected with driving pulleys for moving the carriage back and forth longitudinally of the machine. A horizontally arranged shaft is mounted in suitable bearings on the shelf and extends through the carriage which moves endwise thereon. To this shaft is keyed a rotary cutter for turning the work to the desired shape, either cylindrical or tapered, and the carriage is also equipped with a rotary cutter for forming grooves,

The latheflutes or ribs in the work or for giving an octagonal or other polygonal form thereto.

The fiuting cutter is attached to a radially arranged shaft and is mounted in bearings in a swinging frame whereby the cutter may be brought down upon the work or may be withdrawn therefrom. On said radial shaft is secured a friction roller which engages a disk keyed to the horizontally arranged shaft and through which a rotary motion is given to the fluting cutter. The construction is such that when the fluting cutter is brought down upon the work the friction roller firmly engages the friction disk and the cutter is thereby rotated, but when the fiuting cutter is moved away from the work it ceases to rotate. The machine is first operated to give the desired shape to the work by means of the turning cutter, the fluting cutter being then out of operative position, and then the tinting cutter is moved in such manner as to operate on the work thus shaped. In order to suitably ornament the upper portion of the column, we provide a cutter mounted in a frame which may be swung toward and from the work and held in contact therewith in such manner as to form a bead thereonor to give other suitable shape thereto.

Other features of our invention, together with certain details of construction, will be hereinafter specified.

In the accompanying drawings: Figure 1 shows a side elevation of a machine embodying our improvements with some of the parts broken away. Fig. 2 shows a top plan view thereof, with parts broken away. Fig. 3 is a view on an enlarged scale, and in section, showing particularly the manner of mounting the cutters in the lathe-carriage. Fig. 4 is a detail View, showing particularly the cam used for moving the roller on the fluting cutter shaft into engagement with its driving disk. Fig. 5 is a detail view of the cutter employed for forming a head or other such ornament on the column. Fig. 6 is a detail view of the fluting cutter. Fig. 7 is a view on an enlarged scale and in transverse section of the machine. Fig. 8 is a machineframe, support a shelf- E, on -which' is mounted a carrier F for the lathe-carriage G, which supports the cutters. The carrier F is shown as being in the form of a long narrow hollowstructure, pivotally connected at f to the shelf E and provided with a casting H (Fig. 8), bolted at h (Fig. 7 to the sides of the carrier. This casting is'formed with a recess h andwith a downwardly extending part 75 which extendsthrough an opening in the shelf and connect's with a horizontally arranged part 7 1, carrying a clamping device it. By this means the carrier F may be held on the shelf E. When the devices it are loose the carrier is still prevented from being raised awayfrom the shelf but said carrier is free to swing to a limited extenton its pivot f, for a purpose hereinafter described, but by means of the devices 71 the carrier may be held against a pivotal movement.

A- pattern I isfattached to an angle-iron I, bolted to the shelf E, and this pattern extends horizontally from one end of the machine toward'the other. The pattern of course corresponds with the shape of the article to be produced. The carriage G carries a roller 9, engaging the pattern, and this roller is held against the pattern by a weight J carried by a lever j, pivoted at j, and connected by a rod J to the-carrier F in the manner shown in Fig. 7. Inasmuch as the carrier is pivoted at one end, as indicated at f, the weight tends to draw the opposite end of the carrier toward the work.

The lathe-carriage G is formed with a downwardly projecting lug g, which is formed as a nut and engages a horizontally arranged screw-shaft K,-mounted in suitable'bearings on the carrier F and provided with pulleys, L, L, L for driving it in 013'- po'site directions. By this means the lathe carriage may be'movedback and forth endwise of the machine, being supported in supports a sleeve Q, which is held firmly in place on said post.

' The grooving or fiuting cutter R is secured to a radial shaft r, carried by a swinging frame S, mounted to turn on the sleeve Q: Thisframe'has arms 8 through which the shaft r extends and one endof the shaft carries a roller 5, which bears at times on a friction disk T keyed at t to the shaft N rotating therewith and sliding endwise thereon. The frame S has secured to it at u an arm U carrying a bolt u, engaging a stationary cam U fixed to the sleeve Q- The cam is formed with a recess a to receive'the head of the boltu, at which time the roller 8 does not press tightly against the disk T but when the bolt is withdrawn from the recess of the cam and engages the fiat face thereof the roller .9 presses firmly against the disk T and the cutter shaft is rotated. It will therefore be understood that the work in the rough is placed between the head and tail stocks and rotated. A pattern I of suitable form is secured to the machine; and rotary movement is given to the shafts K' and N while the cutter-frame S is held on its support T in such position as to hold the fiutingcutters away from the work. As the shafts rotate the cutter M turns the work gradually'from oneend to the other, giving to it a form correspondingwiththe pattern used. Said cutter, in the; machine shown, moves gradually from the tail stock'toward from the position shown by full lines in Fig.

7 to that shown by dotted lines therein in order toengage the work. Before doing this, however, the driving belts of the headstockare shifted so as to'stop the-rotation of the work and the work should then be locked against rotary movement whilexthe:

grooving operationis inprogress In Fig." 2 we have shown how groovesare formed 1n the cyllndrical portion of the column. At this time'the carrier F should be disposed parallel with the axis of the lathe and should be held firmly'in place during'the operation. The'screw-sha-ft K causes the carriage to move from one end of the column towardthe other while the shaft N imparts a rotary movement to; the fiuting cutter. hen the end-of a groove-is reached the frame S may be swung back and the screw maybe reversed toreturn-the carriage tostarting position; Inv order to properly space: the" distancebetween the grooves or flutes we preferably form the fast pulley C with a plurality of concentric annular perforations 0 adapted to receive a pin 0 on a lever C pivoted to the lathebed. By these devices the work may be held in the desired position while being grooved and may be moved to the desired extent to space the grooves or flutes on the work at the proper times.

It is sometimes desirable to form a bead on the upper part or neck of a column or to otherwise ornament it in a similar way. For this purpose we employ a cutter V of suitable shape, carried by a swinging frame V, pivoted at U to an adjustable bracket v attached to the lathe-bed. The frame V is provided .''ith a handle 11 and it is formed with grooves to receive the cutter V which is clamped in the frame by a bolt '0 In order to hold the cutter in proper relation to the work we employ a cam WV pivoted to the frame V and having a cam surface Q0 which bears on the work. This cam may be adjusted and then rigidly fixed to the frame V by a bolt to.

lVe have shown in the drawings one specific way of carrying out our invention. The machine is adapted to form columns, posts and other articles of various sizes, of various shapes, and with different "kinds of ornamentation. The general shape of the article is governed by the form of the pattern employed. By means of the rotary cutter M, the movement of which toward and from the axis of the work is governed by the pattern, the column may be made partly cylindrical and partly tapered or wholly cylindrical or wholly tapered. When flutes, beads or grooves are formed longitudinally in the article the pattern is not necessarily employed as these flutes may be formed in a direction parallel with the axis of the work, but it is obvious that the grooves may be formed in an inclined direction if a suitable pattern is employed. It is also obvious that by employing suit able cutters longitudinal beads may be formed instead of grooves or channels, and it is also possible to give tothe article an octagonal or other polygonal form by employing a suitable cutter in place of the cutter R, illustrated in the drawings.

\Vhile the machine is especially intended for working on wood some features of the invention may be employed in metal working machines.
